Abstract-In this paper, a full-wave analysis technique of lossy substrate integrated waveguides, based on the dyadic Green's function of the parallel plate waveguide, is presented. The field inside the waveguide is expressed in terms of cylindrical vector wave-functions and the finite conductivity of the top and of the bottom plates, and of the metallic vias are taken into account. Losses into the dielectric substrate are also included. Coaxial ports are considered as sources and self and mutual admittances are evaluated. Cases of practical structure taken from literature are presented showing a very good agreement with the most used commercial software.

An appropriate choice of conductor and the dielectric material can reduce the involvement of first two losses [9].

In this paper a laminated waveguide fed DR Antenna is investigated. It can use for moderate power military applications. Cylindrical DRA is excited by two closely spaced asymmetric longitudinal slots on the broad wall of the laminated cavity are responsible for producing three different frequency bands. Parametric study of slots has been done with the help of commercial software ANSOFT HFSS. All the bands have sharp rejection. The final model of the antenna is simulated, fabricated and experimentally measured. Measured results are in quite accordant with design results. SIW feeding structures have small losses, moderate power handling capacity, low costs, compact sizes and can be seamlessly integrated with planar circuits. At all the bands 9.76 GHz, 10.53 GHz and 11.8 GHz resonant frequency, the antenna shows 56 MHz, 160 MHz, and 250 MHz impedance bandwidth (for VSWR<2) with 6 dB,6.2 dB and 6.8 dB gain respectively. Simulated and measured results reveal outstanding performance with a cross-polar level of 29 dB lower than that of the co-polar level at 9.76 GHz, the cross-polar level of 32 dB lower than that of the co-polar level at 10.53, GHz, and similarly cross-polar level of 30 dB lower than that of the co-polar level at 11.8 GHz.

“…As perdas em guias SIW proveem principalmente de perdas no dielétrico e no condutor, dado que as perdas por radiação são praticamente nulas na banda de operação 1,5,6 , pois a onda eletromagnética está praticamente confinada no interior do guia, entre as paredes metálicas superior e inferior que o compõem, o que minimiza as perdas por radiação e induções eletromagnéticas devido a radiações externas.…”

This research work presents a detailed study about substrate integrated waveguide (SIW) operating in microwave frequencies based on rectangular waveguides (RWG) theory. The study about SIW associates equations presented at the literature and uses electromagnetic simulations to develop a well-defined design procedure. Is considered the integration between substrate integrated waveguides and microstrip line, designing transitions between these two structures with the aim to provide impedance matching and make possible the characterization in microwave . Is shown a sensibility analysis of the waveguides and filters performance in SIW technology to evaluate the layout differences caused by manufacturing process.With the experimental results and simulation results was possible validate the design procedures and the manufacturing process of the SIW circuits operating in microwave frequencies.
